The dissolved oxygen concentration in the wastewater treatment process (WWTP) must remain a specific range while factory operates. augmented positive identification (PID) controller with nonlinear element (sigmoid function) is proposed to assure stability and reduce uncertainties direct reuse/recycling model. gains (PID sigmoid for uncertain processes are tuned using particle swarm optimization...

Logistic regression is a commonly used classification algorithm in machine learning. It allows categorizing data into discrete classes by learning the relationship from given set of labeled data. learns linear dataset and then introduces nonlinearity through an activation function to determine hyperplane that separates points two subclasses. In case logistic regression, most perform binary clas...

The contrast of an image is a feature which determines how image looks better visually. In this paper, we are analysing the capability of activation functions for contrast enhancement. Activation functions are classically used in neural network. In this paper, Activation function creates a mask which is operated on the image on pixel by pixel basis. On the basis of activation function the pixel...

This article proposes a hypothetical model for determining rate of diffusion of an innovation in a system. The model modifies Everett Rogers’ S-curve using an index created from Gartner’s hype cycle phases. Rogers’ model for technology innovation adoption demonstrates that cumulative technology diffusion in a system from zero through the late majority adopters’ phase forms a curve resembling th...

This paper addresses the problem of separating concurrent speech through a spatial filtering stage and a subsequent time-frequency masking stage. These stages complement each other by first exploiting the spatial diversity and then making use of the fact that different speech signals rarely occupy the same frequency bins at a time. The novelty of the paper consists in the use of auditorymotivat...
